Chronic total occlusions: A European global perspective
Treatment of chronic total occlusion (CTO) lesions still represents the last frontier for the interventionalist. Although the most important cause of procedural failure is the inability to cross the occlusion with the guide wire and to reach the distal true lumen end, other factors may prevent balloon crossing and final recanalisation. Moreover, the recurrence rate of restenosis and reocclusion is higher compared with other subsets of lesions. Data obtained over the past decade have shown that successful recanalisabon of CTO provides long-term outcome improvement, left ventricular ejection fraction improvement, electrical stability of myocardium and improved tolerance for future coronary ev…
Percutaneous Coronary Revascularization for Chronic Total Occlusions A Novel Predictive Score of Technical Failure Using Advanced Technologies
Objectives The aims of this study were to describe the 10-year experience of a single operator dedicated to chronic total occlusion (CTO) and to establish a model for predicting technical failure. Background During the last decade, the interest in percutaneous coronary interventions (PCIs) of chronic total occlusions (CTOs) has increased, allowing the improvement of success rate. Methods One thousand nineteen patients with CTO underwent 1,073 CTO procedures performed by a single CTO-dedicated operator. The study population was subdivided into 2 groups by time period: period 1 (January 2005 to December 2009, n = 378) and period 2 (January 2010 to December 2014, n = 641). Observations were ra…
Retrograde Recanalization of Chronic Total Occlusions in Europe: Procedural, In-Hospital, and Long-Term Outcomes From the Multicenter ERCTO Registry.
BACKGROUND A retrograde approach improves the success rate of percutaneous coronary interventions (PCIs) for chronic total occlusions (CTOs). OBJECTIVES The authors describe the European experience with and outcomes of retrograde PCI revascularization for coronary CTOs. METHODS Follow-up data were collected from 1,395 patients with 1,582 CTO lesions enrolled between January 2008 and December 2012 for retrograde CTO PCI at 44 European centers. Major adverse cardiac and cerebrovascular events were defined as the composite of cardiac death, myocardial infarction, stroke, and further revascularization. RESULTS The mean patient age was 62.0 +/- 10.4 years; 88.5% were men. Procedural and clinical…
